Context: Calculate pH of 0.10 M ethanoic acid (( K_a = 1.8 \times 10^-5 )).
Maths: Solve ( K_a = \fracx^20.10 - x \approx \fracx^20.10 ) → ( x = \sqrt0.10 \times 1.8\times10^-5 = 1.34\times10^-3 ) M → pH = 2.87.
Contextual note: Approximation valid if ( x \ll 0.10 ). Always check. Introduction to Contextual Maths in Chemistry .pdf

Chemistry demands rigorous handling of units (mass, amount, volume, energy). Dimensional analysis ensures equations are physically meaningful.

Example: Convert a rate constant ( k = 0.05 , \textL mol^-1 \texts^-1 ) to ( \textm^3 \textmol^-1 \texts^-1 ).
